Wood’s Powr-Grip PT4FS10TAIR - Manual (Page 3)

Rev 2.0/12-12 1 PT4HV11FAIR: #35141
SPECIFICATIONS
Model Number: PT4HV11FAIR
Description: Designed for use with a crane or other hoisting equipment, the PT4HV11FAIR lifter
employs vacuum to hold a load for lifting, and it provides powered 90° tilt
movement for load manipulation.
Power Source: Compressed air, 80-150 psi [550-1035 kPa] line pressure, 4 SCFM [113
liters/minute] @ 80 psi [550 kPa]
Vacuum Pads: Four 10" [25 cm] nominal diameter, lipped (Model HV11), standard rubber, spring-
mounted (¼" [7 mm] travel), with #60 filter screen and closed-cell foam rings for
applications on rough or textured surfaces.
Pad Shutoffs: Manual valves control vacuum flow at adjacent pads.
Pad Spread: (to outer edges)
Minimum: 19" x 49" [482 mm x 1244 mm]
Maximum: 19" x 85 3/4" [482 mm x 2178 mm]
Load Capacity: (rated at 16" Hg [-54 kPa] on clean, smooth, nonporous flat surfaces 1 )
Per-Pad: 150 lbs [68 kg]
Maximum: 600 lbs [270 kg]
Lifter Weight: 150 lbs [68 kg]
Tilt Capability: Powered, 90°, continuous-duty type with adjustable-flow valves to control tilt
speed; Standard speed = approx. 8 seconds per tilt travel in one direction. 2
Vacuum Pump: Venturi type, 2.8 SCFM [79 liters/minute] nominal vacuum flow @ 80 psi [550 kPa]
Vacuum Reserve Tank: Vacuum reservoir helps prevent immediate vacuum loss in case of power failure.
Vacuum Gauge:
Dial gauge indicates current vacuum level in positive inches of Hg and negative kPa.
Options: See separate instructions about optional features.
Operating Elevation: Maximum = 10,000 feet [3048 meters]
Operating Temperatures: 0° to 120° F [-18° to 49° C]
Service Life:
This lifter is designed to have a service life of at least 20,000 lifting cycles, when
used and maintained as intended. Vacuum pads, filter elements and other wear-out
items are excluded; see MAINTENANCE and REPLACEMENT PARTS LIST for more
information. For the D ISPOSAL OF THE L IFTER after its service life, see INTENDED
USE.
ASME Standard BTH-1: Design Category "B", Service Class "0" (see www.powrgrip.com for more
information)
Hose Routing Diagram: One or more hose routing diagrams are provided in the final section of this
INSTRUCTIONS manual for reference when servicing the lifter or troubleshooting a
deficiency.
!!-CE-!! Note: This symbol appears in the INSTRUCTIONS manual only when requirements of a CE Standard are different from
requirements of other standards that also apply to this vacuum lifter. CE requirements are mandatory in geographical areas
where CE Standards apply, but may be optional in other locations.
